1S-1S-8D:CMD-ADD 都以一个 IO 输出且为 SDR 模式,DATA 则八个 IO 输入输出且为 DDR 模式。 为了灵活配置各协议,在 CMD-ADD-DATA 单个完整传输中,各部分结构都可为 SDR/ DDR 以及 IO 独立配置, 此独立配置以查找表的方式存储,详细见。本节仅仅列出典型协议行为。
No configuration start. The xSPI IP defaults into SPI mode (1S-1S-1S) upon reset, with a command 8’h03 and access to the first 16MB of external address space. Either AXI3 or AXI4 support, with a parameterized bus width ranging anywhere from 16 bits to 1024 bits wide. ...
汽车启动后,高分辨率显示屏需要立即显示出仪表盘、导航地图,以及可支持ADAS的后视摄像机画面等, 符合xSPI规范的8通道SPI NOR Flash即时启动的特性可以将整个过程缩短到1s以内,对不满于当前汽车启动时ADAS系统缓慢上电反应的绝大部分消费者而言,这是一个很关键的指标。 此外,随着芯片工艺和技术的进一步优化,在未来,...
我在e2e论坛里看到有人说x-loader spi载入u-boot特别慢,所以想动手之前了解一下慢到什么程度,还有没有实用价值。 1S以内,我这边几个做工控的客户都用了这种方式,速度都OK 向上0True向下
23.如图2所示,在一个实施例中,隔离电源模块采用rb-3305shp转换器,rb-3305shp系列dc/dc转换器设计用于隔离或转换直流电源轨、成本很低,它支持1kvdc/1s或2kvdc/1s隔离,工作温度范围为-40℃至+85℃,且支持连续短路保护。可将p3v3与gnd转换为p5v_can和gnd_can,这两组信号相互独立隔离。
例如,有5个待处理的任务1、2、3、4、5,其中任务1的任务时长是3s,任务2的任务时长是2s,任务3的任务时长是1s,任务4的任务时长是2s,任务5的任务时长是1s,controller的寄存器组一共有4个a,b,c,d,为了用最短时间完成对多个任务的操作,controller将任务1分配给寄存器组a,任务2分配给寄存器组b,任务3和5分配...
